I he vessel walls break down; polynuclear ACUTE SUPPURATIVE PULPITIS 121 leukocytes, and, to a less extent, red corpuscles, are attractedtoward certain bacteria in enormous quantities and thereby becomethe progenitors of pus corpuscles. A circumscribed collection ofthis freshly formed pus is designated as an abscess. In its earlystages the abscess is usually confined to a horn of the pulp and islocated directly opposite the point of entry of the infection, namely,the minute opening into the pulpal covering. Above the abscessa wall of inflamed tissue denotes the line of demarcation, andthe remaining pulp presents the typical picture of a severe acuteinflammation. With the progressive advance of necrobiosis, thefinal submission of the whole pulp to the infection is only a questionof time. It should be observed that the process of destruction isin most cases intensely acute. The nerve fibers preserve theirintegrity to the Aery end of the struggle. As the pulp is confined. Fig. 07.—Acute suppurative pulpitis. within an unyielding wall of dentin, the increasing pus producescompression and irritation of these fibers, and hence the persistentintolerable pain. If the pus does not remain localized, but infiltrates the spacesbetween the connective-tissue cells, a phlegmonous suppuration ofthe entire pulp results which quickly kills it. Through the agenciesof specific proteolytic ferments the necrosed tissue changes togangrene. In multi-rooted teeth, especially the molars, this purulo-gangrenoug type of pulpitis is most frequently observed. In suchcases one root canal may be found to be totally gangrenous, whileanother canal may contain a pulp remnant in an advanced state ofsevere acute inflammation. Subjective Symptoms.—Very violent, throbbing, continuous pain,increasing on entering a warm room, on lying down, or on theapplication of heat. Cold a
